Looking for an isotropic RF strength meter with PC interface

[0xfede]

Hello all,

I'm looking around for an isotropic RF strength meter with PC interface. The main use is as a feedback for RF generator to check CISPR11 immunity precompliance. The radiated level should be 10V/m and 20V/m (+-10% IIRC) from 70MHZ to 2.7GHZ.
There are a lot of low cost devices around but none offers a PC interface and their accuracy is a big question.
There are a few active antennas (that I can connect to a SA) but I don't have any experience.
Then the classic Chavin Arnoux CA43 could be a solution but it is rather expensive (3k€ + VAT).

I don't need a class A instrument, just something to be in the right ballpark.

Any advice?

Thanks,
